Steam loco operation

[nkp_174]

The DM&IR operated 0-10-2s, 2-10-2s, and 2-8-8-4s until 1963.

I know they rostered steam into 1963, but I don't think it operated past 1960. UP also had steam stored but still on roster until 1963, though they last used it in 1959.

I've seen films of them running in 1961. I don't know that they were being used in 1963...but they definitely stretched their rods in 1961.

Here are a coupledetails that matter more for a late-1950's/early 1960's modeler than for the more classic early 1950s:
-1957, journal boxes had to be cast into the truck frames (no Andrews trucks).
-1958, no cast iron wheels (wheels with ribbed backs)
